and Health
The thyroid hormones play an important role in regulating metabolic processes within the human body, and as such are closely associated with overall health. An abnormal level of thyroid hormones can be suggestive of a disorder and requires further testing to determine the exact cause. One of the most valuable tests used when diagnosing thyroid disorders is the measurement of the quantity of thyroid-stimulating hormone (TSH) in the blood.
What is TSH?
Thyroid-stimulating hormone is a hormone produced and secreted by the pituitary gland in the brain. It binds to receptors on the surface of the thyroid gland, triggering the release of thyroxine (T4) and triiodothyronine (T3). These hormones travel through the bloodstream to impact the supply of energy and oxygen to cells, as well as growth and development.
Measurement of TSH Levels
When measuring TSH levels, a simple blood test is performed. Having a high level of TSH in the bloodstream can be indicative of a hypothyroid, or underactive, state. This can be caused by inflammation or damage to the thyroid, hereditary conditions, autoimmune diseases,radiation therapy and side effects of certain medications. On the other hand, having a low level of TSH can indicate an overactive thyroid, or hyperthyroid, state. This can be caused by inflammation, excess iodine, autoimmune disorders, and benign or malignant tumors.
Reliability of TSH Test
The TSH test is considered to be one of the most reliable hormone tests when it comes to diagnosing thyroid disorders. It is used as a primary diagnostic tool, and often additional tests will be used in combination to confirm and pinpoint the exact cause. The reference range for a TSH test varies depending on the lab and the method used to measure TSH levels.
Maintaining Good Thyroid Health
Keeping your thyroid healthy is an important part of overall health and wellbeing. Eating a balanced diet and avoiding foods that are high in sugar, saturated fats, and processed ingredients is key. Making sure to get ample amounts of rest, exercise regularly and manage stress levels is also important for thyroid health. Additionally, it’s important to get regular check-ups that include measurements of TSH levels to make sure everything is functioning properly. If you suspect you may have a thyroid disorder, it is important to see your doctor to get a proper diagnosis.
